   <span class="function"><strong>ingres_autocommit()</strong></span> is called before opening a
   transaction (before the first call to
   <span class="function"><a href="ingres_query.html" class="function">ingres_query()</a></span> or just after a call to
   <span class="function"><a href="ingres_rollback.html" class="function">ingres_rollback()</a></span> or
   <span class="function"><a href="ingres_commit.html" class="function">ingres_commit()</a></span>) to switch the
   autocommit mode of the server on or off (when the script begins
   the autocommit mode is off).
  </p>
  <p class="para">
   When autocommit mode is on, every query is automatically
   committed by the server, as if <span class="function"><a href="ingres_commit.html" class="function">ingres_commit()</a></span>
   was called after every call to <span class="function"><a href="ingres_query.html" class="function">ingres_query()</a></span>.
   To see if autocommit is enabled use, 
   <span class="function"><a href="ingres_autocommit_state.html" class="function">ingres_autocommit_state()</a></span>.
  </p>
  <p class="para">
   By default Ingres will rollback any uncommitted transactions at the end of
   a request. Use this function or <span class="function"><a href="ingres_commit.html" class="function">ingres_commit()</a></span> to
   ensure your data is committed to the database.
